The example fans here are a Seasonic MagFlow and an MSI Silent Gale P12.Īll-rounders, as the name suggests, are fine in any area and are not “specialists”. All-round fans combine aspects of both specialized fan types. These fans are less specialized, but they offer solid performance in any position and you can’t use them in a wrong position.
In most cases, the fan blades are size-wise between the special forms, but the space between them is small by increasing the number of fan blades. These combine peculiarities of both designs. The trend in recent years is strongly in the field of all-round fans.

These values are specified for almost all fans, but what does it actually mean? First, let’s take a look at typical representatives of each genre and how to recognize them.Īirflow fans have rather few fan blades, usually seven, which are relatively narrow and have a lot of space between them. Or more often found under the English terms “airflow” and “static pressure”. Static-Pressure fans push less air with more force even around obstacles.Airflow fans entrain air and work well when not slowed by obstructions.Application in the case – Airflow or Static Pressure?.If you are interested in water cooling for PCs, please see my further blog Using Water Cooling in Electronics Thermal Management. This blog focused on CPU temperature prediction for an air cooled PC.

However, there is always room to improve. These results closely match those of a real PC I recorded (Is My PC Too Hot? ), and demonstrates the validity of the case set up. The maximum temperature was recorded at the junction, inside the CPU, reaching 63 deg C. PC cooling system – Rear View CPU temperature results CPU temperature – thermal simulation result
Then we solved the model and let the magic happen! The flowrates of the fan were adjusted to around 40 cfm which is more typical of PC cooling fans. We decided to set the power sent to the CPU to be 65 W, as this was the average power the CPU received when I ran a stress test (Is My PC Too Hot?). A steady state solution type was used to determine the temperature the CPU would eventually reach if the system was to run at a constant power. Once the PCB with all its components were inserted into the case, the model was ready to be set up. Setting up the CFD simulation of the PC cooling system The warm air is subsequently forced out via the fan at rear. The rate of heat transfer is amplified by the fan which sits upon the heatsink by increasing the rate of air flowing through the heatsink. The heatsink conducts heat from the CPU and transfers this to the passing airflow. Well, 2 fans at the front provide forced airflow into the case, which then passes over the PCB and its components. How does this all work? PC Airflow – CFD simulation (Simcenter Flotherm XT) However, this model aims to provide a good representation of typical gaming PC cases readily available. Some of these dimensions were a bit tricky to measure due to internal wires inside the case getting in the way. The dimensions used in this model were measured by myself based on my own PC.

For CFD, I am using Simcenter Flotherm XT which is an electronics cooling CFD software that utilizes a CAD based enabling geometry engine, allowing for a seamless transition from model creation to setting it up for a CFD virtual test studies. Here it is! Inspired by my own PC cooling system, I have designed the PC case to be used in our CFD simulations by creating case geometry using CAD.
